﻿If you look, the "Stacks" is the same thing as "Group similar taskbar items"...just apple took it a little further...

Shocking rip off with the dock .... but I disagree with your assessment of what Stacks is - group similar taskbar items does not give you a stack view of the contents of a folder. Let's wait for the video stream, but I bet it is more in line with
this.

Honestly, Leopard looks rather disappointing. I mean, it'll be a nice operating system and all, but there weren't really any "Vista killers" that the community had been hoping for. Most of the features are already in Vista, albeit not as polished as Apple's
solution (Time Machine being the obvious example). And more of the features that aren't in Vista aren't particularly compelling. Stacks could be nice, but they've been sitting on that for years. I remember reading about them in Bruce Tognazzini's
Tog on Software Design (1995)--I guess they still beat Cairo though...

Is there any summary (e.g., bullet points) on the developer features? I'm aware of CoreAnimation and ZFS, but haven't heard much else. It almost seems silly that the big news is yet another way to render HTML on Windows.

give it 5-6 years and all the major operating systems will have all the same features ripped off from eachother, just built around a different kernel and structure.
from watching the hightlights of leopard i actually found myself wanting a mac, which is something i never thought i would say.
unfortunately i still live in a windows world, it's what i use everyday at work as an admin. so it's likely to make my life easier if i just stick with it at home.
i can see myself not making a switch, but perhaps moving towards a dual boot scenario.
either way, it does look interesting.
